Candle batch scaler — multiply one jar into a pour list
Enter wax grams per candle, how many jars, waste %, and fragrance load to see total wax, FO grams, and how many bags to buy for the batch.
Results
Wax (exact): 1550 g
Wax with waste: 1627.5 g
Fragrance oil: 130.2 g
Bags to buy: 4
Formula
wax=per×count; withWaste=wax×(1+waste); FO=withWaste×load; bags=ceil(withWaste÷bag)
Worked steps (check these)
- Wax (exact) = 155 × 10 = 1550 g
- Wax with waste = 1550 × (1+0.05) = 1627.5 g
- Fragrance oil = 1627.5 × 0.08 = 130.2 g
- Bags to buy = ceil(1627.5 ÷ 500) = 4

Batch FAQ
- Where does wax-per-candle come from?
- Use Candle wax calculator for one jar, then paste that wax grams here.
